Electrode Compositions for High-Temperature Polymer Electrolyte Fuel Cell (HT-PEFC)

Abstract

One theoretical advantage of High Temperature Polymer-Electrolyte Fuel Cells (HT-PEFC) is the higher kinetic of the anode and cathode reaction. Whereas on the anode side the higher kinetic can be achieved practically, the kinetic on the cathode side is in practice lower than in low temperature PEFCs. In this paper different kind of electrode compositions for anode and cathode are prepared to improve the interface between an acid-base blend membrane (Polybenzimidazol-sulfonated Polysulfon) in respect to the cathode kinetic and the ohmic resistance of the Membrane-Electrode-Assembly (MEA).
